Z '0 all whom it mdy concern:

Be it known that I, FRED Wnonnn, a-citizen of the United States, residing in Fairport, in the county of Monroe and State of New York, have invented a new and useful Improvement in Double-seaming Machines, of which the following is aspecification.

My invention relates to improvements in double seaming machines. l

The object of my invention is to provide double seaming machine of a simple, e 'cient and durable construction, which will be automatic in operation and of high capacity, enabling the heads or covers to be seamed on the bodies of cans very rapidly and cheaply, and in which at the same time the motion of the moving parts will be relatively slow and easy, which will operate to produce uniformly perfect and hermetically tight double seams. The machine embodying my invention by which I practically accomplish this object ori/result, comprises in cooperative combination, a large, stationary, circular or convexly curved seaming tool having a plurality of separate and individually adjustable seam formin segments, and a plurality of separate and individually adjustable seam closing segments, a can carrier having a plurality of pairs of upper and lower rotary can ho ders or chucks thereon, the spindle of one can holder chuck of each pair having a gear meshing with a stationary gear for rotating the cans in the can holders as they are conveyed around by the carrier and thus rotated in contact with the stationary seaming tool, one of the can holders or chucks of each pair bein vertically movable to clamp and unclamp (Ire cans, a feed device for automatically feeding or delivering the can heads or covers upon the can bodies, and a feed device for automatically feeding or delivering the can bodies with the heads or covers thereon onto the lower can holders or chucks of the carrier as the carrier rotates continuously.

My invention also consists in the novel construction of parts and devices and in the novel combination of parts and devicesherein'shown and described andmore particularly specified in the claims.

L In the accompanying drawing forming a part of this specification, Figure 1 is a plan view of a double seaming machine embodymg my invention, a portion of the can body conveyor being broken away. Fig. 2 is a. front elevation. Fig. 3 is a detail horizontal section on line'33 of Fig.2. Fig. 4 is a detail horizontal section on line 44 of Fig. 2. Fig. 5 is a detail side elevation showing the can body feeder or placer. Fig. 6 is a horizontal section on line 6 -6 of Fig. 2. Fig. 7 is a detail sectional view of thecan head or cover feed device. Fig. 8 is a detail section of the seaming tool through one of the seam forming segments. Fig. 9 is a detail section through one of the seam closing segments.

In the drawing, A represents the frame of the machine; B is the stationary seaming tool; C is the. stationary gear for rotating -the can holders; D I), u per and lower rotary can holders or chuc s, E the continuously rotating carrier upon which the rotary can holders are mounted, F the can body feeder or placer for feeding or delivering the cans one by one onto the lower chucks or holders of the carrier, G a can conveyer and H a can head or cover feeder for feeding or delivering the can heads or covers one by one onto the can bodies.

The frame A may be of any suitable kind or construction adapted to givesupport or mounting to the other parts or devices of the machine.

The large, stationary, convexly curved or circular seaming tool B, preferably comprises a series or plurality of separate and independently adjustable seam formin segments 1;, preferably six in number, an a series or plurality of separate and independently adjustable seam closing segments 1), adjustably secured to a ring B by set screws 7/ and adjusting screws b so that each successive tool segment I) b'or b b may be set or adjusted slightly radially outward in re- 1) preferably have the of the can body and can head or cover or the seam-formed by the interfolding or curling of same. v

The stationary gear C by which the rotary can holders are rotated-as they are conveyed around the circular or convexly curved seam-' ing tool is preferably an ordinary spur gear and may be formed of a separate piece, or integral with the ring B or with a portion of the frame, as may be preferred.

The can carrier E has an upright shaft or spindle E journaled in the frame of the machine, and is vcontinuously rotated from the driving shaft N, through suitable gearing; the same preferably comprising a spur gear a on the driving shaft N meshing with a spur gear m on the countershaft M, having a bevel gear mmeshing with a bevel gear E on a sleeve E havin a spur gear E meshing with a spur gear TV on shaft E said gear E also meshing with a gear E on the upright shaft E which bears at its upper end a spur gear E which meshes with the internal gear E on the lower portion or spider of the carrier E. .The can carrier is preferably furnished with six can holder yokes E upon which the upper and lower rotarv can holders or chucks D D are mounted, the can holder yokes being adjustably secured tothe can carrier by set screws E The s indle d of each of the upper rotary can holders or chucks D is furnished with a spur gear d meshing with a stationary gear C to cause the can holder chuck to be axially rotated as the carrier E travels around the stationary gear. The spindle d of each of the lower can holders or chucks D may also be (preferably positively driven vided with a further gear al meshing with a gear (11 on the spindle d on the lower chuck or holder D The upper and lower can holders or chucks D D of each pair are thus caused to be positively driven or rotated in unison with each other. The lower can holders or chucks D are preferably the ones which are made vertically movable to clamp and unclamp the cans between the upper and lower chucks. The spindle d of the lower chuck D preferably has a splined connection d with 1ts geard to permit of the raising and lowering'movement of the lower chuck. The lower chuck or can holder D is preferably moved up and down as required to clamp and unclampthe can and held or maintained in its raised or clamping position during the seaming operation by means of a stationary track or cam O on the frame of the'machine, which is engaged by a roller al on a slide (i the upper end of which-engages the lower end of the chuck spindle d The high portion 0 of the stationary cam or track 0 hold or maintains the lower chuck D in its raised or placer F which operates to push the can from the feed table P onto the holder as the holder moves into registry or cooperative relation with the can feeder or placer F.

The can feeder or placer F prefera ly has a reciprocatory movement horizontally and radially toward the center of the carrier E. The can feeder or placer F is preferably furnished with a pair of outer can head centering pins f, which, by engagement with the seaming flange 0c of the can head or cover X serve to center the can head with the can body in conjunction with an inner pair of can head centering pins f which are preferably mounted movablyon the yoke E of the carrier E so that this inner pair of can head centering pins f may be moved or rocked slightly out of the way after the can has been placed on the lower chuck D by the feeder or placer F and before the lower chuck D moves upward to clamp the can between itself and the upper chuck or holder D. The can feeder or place-r F has a stem or slide f 'and is preferably operated by a cam f on the shaft 7 driven by the main shaft through a lever F, a spring 7 being provided to return the can feeder or placer F to position.

The inner or movable pair of can head centering pins f are preferably rocked or moved out of the way by means of a bent lever f", the lower arm f of which is enga ed by a spring secured to the yoke E he can bodies with the can heads or covers in place thereon are preferably conveyed or moved along the feed table P into position in front of the reciprocating can head feeder or placer F by means of a can conveyer G, having fingers 9 adapted to engage the cans. The conveyer Gr preferably consists of an endless belt or chain mounted upon a pulley G The feed table P is preferably furnished with side guides P The can heads or covers X are preferably fed or delivered one by one to each can body X from the can head or cover holder S by a movable feeder H, having upper and lower fingers or blades h h adapted to release the lowermost can head or cover from the pile or stack at each movement of the feeder. The feeder is preferably intermittently operated as required by camlinks k connected to the arms of a pair of rock shafts h which have further arms k connected to the operating rod or link b. As the cam links it continuous motion.

is pretfierably sufiiciently large in diameter to cause each can to make at least ten complete axial rotations or six revolutions in contact with the seam forming portion of the tool and four revolutions in contact with the seam closing portion of the tool. The large diameter of the seaming tool 13 in respect to i the diameter or size of the can gives an increased line of contact of the tool with the can fiangesor seam during the seaming operation, and thus serves to insure perfection Y and tightness of the seam as compared with the result secured by the ordinary rotary small diameter seaming roller or tool commonly used in double seaming machines. The seam forming segments 1) of the stationary seaming tool B preferably have substantially the same contour of double seaming groove as that ordinarily employed in double seaming machines for the rotary small diameter seaming rollers. And the same is true of the seam closing segments b of my seaming tool B.

As the rotary can carrier E has a large or any desired number of axially rotatable can holders thereon, and as'it may move at a relatively slow speed, while the machine as a whole has a high capacity, the reciprocating can feeder or placer F may be readily operated to feed or place the cans accurately and properly uponeach lower can holder or chuck D as the same comes into can receiving position while the carrier E is under By adjusting the can holders D D radially in and out on the carrier E, the machine is adapted to operate on cans of diiierent diameters. The can holders D D may be adjusted an amount equal substantially to the sum of the depth of the teeth on the intermeshing gear and pinion's C and d and the amount of adjustment allowed by the sectional seaming tool B.
